    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 v(DwU!  
    P$Z}  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: V0K16#}1gM  
    enableservice('AutomationServer', true) JD6aiI!Su  
    enableservice('AutomationServer') t, U) ~wi  
    >+cSPN'i>  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 AXwaVLEBQ  
    \K}-I  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 3&'2aW   
    1. 在FRED脚本编辑界面找到参考. [SVhtrx|%  
    2. 找到Matlab Automation Server Type Library C ye T]y  
    3. 将名字改为MLAPP GCDwWCxh

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 dsJm>U)

    现在将脚本代码公布如下,此脚本执行如下几个步骤: qO-9 x0v#  
    1. 创建Matlab服务器。 -LtK8wl^  
    2. 移动探测面对于前一聚焦面的位置。 C5xag#Z1  
    3. 在探测面追迹光线 (n,u|}8Y  
    4. 在探测面计算照度 <aJ $lseG  
    5. 使用PutWorkspaceData发送照度数据到Matlab _;56^1'T  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 r-}-C!  
    7. 用Matlab画出照度数据 >M]6uf  
    8. 在Matlab计算照度平均值 E<>*(x/\e  
    9. 返回数据到FRED中 S,)d(g3>
